浅层地下空间探测中的多道面波谱分析法Multichannel Surface Wave Spectral Analysis in Shallow Underground Space Prospecting
张燕生
摘要(Abstract)：
面波具有能量强、传播过程衰减慢、频散特性等特点,在浅层地下勘查领域中可以弥补其他地球物理方法的不足,受到业内的广泛关注。结合天然源微动和人工面源激发在勘探深度和分辨率上的各自表现,多道面波谱分析法越来越成为主流的面波勘探方法之一。依据城市道路路基结构模型,从面波产生机理检波器排列布设、数据处理流程以及工程应用中应该注意的问题等几个方面,梳理介绍了多道面波谱分析法及相关提取频率速度曲线的方法。
关键词(KeyWords)： 多道面波谱分析法;频散曲线;面波;剪切波;观测台阵;空间自相关法;频率波数法;微动
